First, the deepening of environmental protection connotation

Traditional environmental protection often focuses on reducing pollutant emissions, while modern environmental protection concepts pay more attention to resource recycling and ecosystem protection. This means that in sewage treatment, we should not only achieve the purpose of purifying water quality, but also consider how to maximize the reuse of water resources and how to minimize the secondary pollution generated in the treatment process. In addition, the improvement of public participation is also an important aspect of deepening the connotation of environmental protection, encouraging all sectors of society to participate in environmental protection and forming a good environmental protection atmosphere.

Second, the direction of strengthening the sewage treatment core

1. Technological innovation: adopt more advanced biological treatment technology and physical and chemical methods, such as membrane bioreactor (MBR) and advanced oxidation process, so as to improve the sewage treatment efficiency and ensure the effluent quality to meet the standard.

2. Resource recovery: Recovering useful substances, such as phosphorus, nitrogen and other nutrients from sewage through technical improvement can not only reduce the environmental burden, but also create economic benefits.

3. Energy conservation and emission reduction: optimize the operation mode and equipment selection, reduce energy consumption, and explore the use of renewable energy as a power source to reduce the carbon footprint.

4. Intelligent management: the intelligent management and monitoring of sewage treatment facilities are realized by using information technology means such as Internet of Things and big data analysis, so as to find and solve problems in time and ensure the stable and efficient operation of the system.

5. Public education: strengthen the popularization of environmental protection awareness, especially carry out various publicity and education activities for young people, and cultivate their good habits of saving water and caring for the environment.

Third, the conclusion

Facing the increasingly severe challenge of water pollution, we must deepen our understanding of environmental protection and push the sewage treatment technology to a higher level. This not only requires the government to formulate scientific and reasonable policy guidance and support measures, but also requires enterprises to increase investment in research and development, and it is inseparable from the active participation of every citizen in this "clear water defense war". Only in this way can we jointly protect the precious source of life on this blue planet-water.
